11 6) The boiler should be located as close to the chimney as possible. 7) Do not install this boiler directly on a surface that may get wet. Raise the boiler on a pad.
12 V Knockdown Boiler Assembly Instructions 10 A. Prior T o Assembly 1) Thoroughly inspect the cast iron heat exchanger sections for any shipping damage, i.e. cracks in the castings, broken lugs or punctures due to mishandling. 2) Do not use a damaged heat exchanger section.
13 11 Figure 4: Multiple Base Assembly.
14 12 C. Section Assembly 1) Clean the boiler sections inside and out to remove dirt due to shipping and handling. 2) Clean all nipples and nipple ports with kerosene immediately prior to section assembly . 3) Set the left end section on the base so that the locating lugs on the bottom of the section go inside the front and rear base panels.
15 13 Figure 6: Assembly Of Sections Figure 5: Use Of Nipple Gauge.
16 14 14) Install the tankless coil/s and/or cover plates using the gaskets and 3/8 x 7/8 bolts and washers provided (see Figure 7). 15) T est assembled block for leaks. Unless local codes have other requirements, use the following procedure: a) Run a hose from the water service to one of the lower tappings.
17 15 6) Hang a rear tie rod channel bracket on the 4" stud installed in the left end section (Figure 12a). 7) Facing the rear of the boiler , find the square mounting holes underneath the draft hood. Drop a 5/16 x 5" carriage bolt through this hole and through the hole in the rear tie rod channel bracket.

25 23 VII V enting V ent installation must be in accordance with local building codes, or the authority having jurisdiction, or the National Fuel Gas Code, NFP A 54/ANSI Z223.1 . T ypical vent installations are shown in Figures 20 and 21. The vent system shown in Figure 20 uses a common vent for all boiler modules.
26 6) Lateral venting should slope upwards towards the chimney not less than one inch in four feet. No portion of vent pipe should run downward or have sags.

28 Removing An Existing Boiler From A Common Chimney In some cases, when an existing boiler is removed from a common chimney, the common venting system may be too large for the remaining appliances.
29 27 VIII S team Boiler Piping & T rim Installation 1) Figures 27 shows the recommended near boiler piping for most common types of gravity return steam systems. Use Table 6 to determine the riser, header and equalizer piping sizes for the appropriate boiler model.
30 28 Hydrolevel CG450 – This is a probe type L WCO and is installed in tapping “G”. On the CSD-1 control package, and other boilers with redundant low water cut-offs, the CG450 is the operating low water cut-of f and should be used to control a feeder (if used).

32 f. Boiler Drain Valve - Install with a 3” x ¾” bushing into one of the two return tappings “B”. The drain valve may also be installed in the return piping, but it must be installed in the leg of a tee so that it is directly opposite and as close as possible to the return tapping.

38 36 B. Indirect W ater Heating Piping (S team Boilers) The steam version of the Series 32 boiler is equipped with tappings to permit the connection of a Crown Mega-Stor, or other indirect water heater. In this type of system, hot boiler water is drawn from below the water line and passed through the heat exchanger in the indirect water heater.
39 37 CAUTION • INSTALL BOILER SO THAT THE GAS IGNITION SYSTEM COMPONENTS ARE PROTECTED FROM WATER (DRIPPING, SPRAYING, RAIN, ETC.) DURING APPLIANCE OPERATION AND SERVICE (CIRCULATOR REPLACEMENT, ETC.). • OPERATION OF THIS BOILER WITH CONTINUOUS RETURN TEMPERATURES BELOW 120°F CAN CAUSE SEVERE HEAT EXCHANGER CORROSION DAMAGE.
40 38 DANGER • CONFIRM RELIEF V AL VE HAS THE CORRECT PRESSURE SETTING AND CAP ACITY FOR THE BOILER. • PIPE THE PRESSURE RELIEF VALVE DISCHARGE TO A SAFE LOCATION. • DO NOT INSTALL A VALVE IN THE RELIEF VALVE DISCHARGE LINE. • DO NOT PLUG RELIEF VALVE DISCHARGE.

44 42 B. TANKLESS HEATER PIPING If the Series 32 water boiler is installed with an optional tankless heater, pipe the heater as shown in Figure 32. The components in this system and their functions are as follows: 1) Mixing Valve (Required) - During the heating season, the water exiting the tankless heater may be 180 degrees or more.
45 43 8) Multiple Tankless Heaters - If two tankless heaters are installed in the boiler, it is recommended that each heater be installed in parallel with its own mixing valve, relief valve, flow restrictor, etc.. This will permit either heater to be removed from service for maintenance while still providing some domestic water to the building.
46 44 X Gas Piping 1) Gas piping to the boiler must be sized to deliver an adequate supply of gas for the boiler to fire at the nameplate input with the inlet pressure at the gas valves between the minimum and maximum valves shown on the rating plate.
47 45 XI Control System Wiring WARNING All wiring and grounding must be done in accordance with the authority having jurisdiction or, in the absence of such requirements, with the National Electrical Code (ANSI/NFPA 70).
48 46 6) Once the ignition module detects the presence of a pilot flame, voltage is applied across the main valve, opening the valve and establishing main flame. 7) The way in which the ignition module handles failure to establish pilot or the loss of an already established pilot depends upon the exact ignition module supplied with the boiler .

51 Safety Control Operation T emperature Limit Control (W ater Boilers) – The temperature limit control interrupts burner operation when the supply water temperature exceeds the set point. Maximum allowable water temperature in a water boiler is 250F .
52 50 XII S tart-up and Checkout Use the following procedure for initial start-up of the boiler: 1) Make sure that the boiler is filled with water. 2) Check all new gas piping for leaks and purge piping sections that are filled with air. See the National Fuel Gas Code for additional information on testing and purging gas lines.
53 51 WARNING FAILURE TO FOLLOW THE FOLLOWING PROCEDURE EXACTLY COULD RESULT IN OVER-FIRING OF THE BOILER AND A CARBON MONOXIDE HAZARD. 13) Check the manifold pressure and adjust if necessary. To do this, use the following procedure: a. Connect a manometer to the inlet pressure tap on the gas valve (see Figures 39 - 41).
54 52 16) (Steam Boilers) - Verify low water cutoff operation while the boiler is running. Slowly open drain valve and drain boiler until the water level drops below low water cutoff line. Water still should be visible in the gauge glass when the low water cutoff shuts down the main burners.
